With water scarcity intensifying, wastewater treatment and reuse are gaining popularity. But some methods for killing microbes in wastewater create disinfection byproducts (DBPs) that could be harmful to human health. Now researchers have found that ozone treatment and subsequent chlorination can convert trace amounts of some pharmaceuticals in wastewater into DBPs called halonitromethanes.

A study of seven wastewater treatment plants in the Eastern United States points to two treatment methods - granular activated carbon and ozonation - as particularly promising. Each technique reduced the concentration of a number of pharmaceuticals, including certain antidepressants and antibiotics, in water by more than 95%, the scientists' analysis found.

Coastal wastewater treatment plants may be a nasty but necessary way to handle the effluent from our cities, but a new study by Stanford University indicates that they could also double as power plants to make them energy independent and carbon neutral. By mixing fresh water from the plants with seawater, the researchers say they have the potential to recover 18 gigawatts of electricity worldwide.
